Answer:
Decanitrogen is molecular
Explanation:
Explanation:
An atom is made up of:
- Protons which are the positively charged particles
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
To find the nuclear charge:
We use the effective nuclear charge formula:
Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)
The shielding electrons are the non-valence electrons in the inner orbitals.
For example:
Ne:
atomic number = 10
Effective nuclear charge = 10 - (2) = 8+
Number of non-valence electrons is 2
The effective nuclear charge is 8+
Overall charge:
Charge = number of protons - number of electrons
For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.

The answer will be option D) Tyndall effect.
We can identify a solution if light is not visible from it.
We can identify a suspension if some light is visible from it.
We can identify a colloid if all light is visible from it.
Answer:
People wanted to settle there because it had good living conditions. There was rich soil, and lots of water sources.
I hope this helps!
